EUGENE SCHNEIDER, OF LE CREUZOT, FRANGEQASSIGNOR TO SCHNEIDER & (3115.,OF PARIS, FRANCE, A LIMITED JOINT STOCK COMPANY OF FRANCE.

FIRING MECHANISM OF GUNS.

To all whom it may concern:

Be it known that I, EUGENE SCHNEIDER, a citizen of the French Republic,residing at Le Creuzot, France, have invented a new and usefulImprovement in the Firing Mechanism of- Guns, which is fully set forthin the following specification.

This invention has for its object to provide an improved firingmechanism for guns, and to this end it consists in providing a combinedstriker-carrier and firing tube holder for the breech mechanisms of gunscomprising a plastic breech gas check ring.

It has already been proposed to provide the striker-carrier of suchbreech mechanisms with a head, in which the firing tube is engaged insuch a manner as to produce on the one hand the proper insertion of thelatter in the firing hole (formed in the movable head of the breech gascheck ring) by the engagement of the striker-carrier in the shutter orother part of the breech block, and on the other hand inversely toeffect the extraction of the firing tube case by the withdrawal of thestriker carrier.

In known apparatus of this kind, the engagement ofthe firing tube iseffected generally only along a fraction of the circumference of thecollar of the firing tube case. The consequence of this is that inwithdrawing the striker-carrier, the result of this movement so far asit effects the pulling out of the firing tube case, is not satisfactory,while also the centering of the firing tube case is not sufficientlyassured.

The improvements of the present inven tion have for their object toavoid all those drawbacks. With this object, the firing tube holder isconstituted by a disk fitting the front face of the striker-carrier towhich it is jointed by an eccentric pivot.

This disk is pierced at its center with a lodgment for the bottom of thefiring tube case, and is adapted by displacement about its pivot, to bebrought into a position which allows the introduction of a fresh firingtube into the striker carrier, or the withdrawal of an empty case. Asimple means of engaging the parts is provided between the firing tubeholder disk and the strikercarrier proper. This engagement is preferablyeffected at a point diametrally opposite to the pivot of the disk.

App1ication filed February 14, 1918. Serial No. 217,184.

A practical embodiment of this invention is illustrated by way ofexample in the accompanying drawings in which:

.Figure 1 is a longitudinal axial sectionv of a gun breech provided witha breech block fitted with a plastic gas check ring, all being of anysuitable known type, to which the present improved arrangement ofcombined striker-carrier and firing tube holder is applied. I

Fig. 2 is a side elevation partly in section, drawn to a larger scale,of the combined striker-carrier and firing tube holder, the firing tubeholder disk being charged with a firing tube and shown engaged with thestriker-carrier.

Fig. 3 is a correspondin end view.

Fig. 4 is a side elevation of the parts shown in Fig. 2, wherein thesaid parts are shown in the position for allowing a fresh tube to beinserted or an empty tube to be withdrawn.

Fig. 5 is an end view of Fig. 4t. 7

Referring first to Fig; 1 Ais the breech end of a gun fitted with abreech block B comprising a plastic gas check ring C with a movable headD.

In the example shown, the movable head which is assumed to be screwed ina shutter E, comprises at its rear a nipple F for engaging the body ofthe firing tube case G. The shutter E has a lodgment for the engagementand assembling by any suitable means of the removable striker-carriercombined with the firing tube holder I. In the example shown, it isassumed that this engagement is efiected by means of a continuousscrew-thread H formed on the body of the striker-carrier and adapted toengage in a corresponding internal thread in the shutter E.

According to this invention the firing tube holder consists of a disk I(preferably though not necessarily in a single piece) in the center ofwhich there is formed a lodgment of a section corresponding to that ofthe bottom of the firing tube case.

The disk I is pivoted to the removable striker-carrier H by means of aneccentric axel-pin I this arrangement allowing of the disk being broughtalternatively into the position shown in Figs. 4: and 5 for theinsertion of a fresh firing tube or the withdrawal of an empty case, orinto the position shown in Figs. 2 and 3 Where it is shown engaged Withthe striker-carrier before the Whole is screwed into the shutter E.

In the preferred example shown, the engagement between the disk I andthe body of the striker-carrier H is effected by means of a stud. Hfixed in the front face of the body H, and a groove in the form of' anarc of a circle I cut in the disk I. The curvature of this groove hasfor its center the pivot I of the disk, and the bottom of the groove ispreferably located at a point diametrally opposite to the said pivot.Any other suitable device for securing the disk in position may beemployed.

In the position of engagement the disk I is firmly engaged with the studH asclearly shown in Figs. 2 and 3.

To bring the disk intoone or the other of the positions shown, it ismerely necessary to actuate it by means of the firing tube case Gr.

As a result of" theconstruction the disk I is centered exactly inrelation to'the body of the striker-carrier H, so that the centering ofthe firing tube With relation to the nipple F of the movable head isnecessarily assured as soonas the striker-carrier is in its place in theshutter of the closed breech block.

The bottom of the firing tube case is'held all along its periphery inthe disk I; this arrangement facilitating not only the maintenance ofits centering during its insertion, but also the extraction of the emptycase in the Withdrawal of the Whole mechanism HIG.

As hereinbefore stated, the engagement or hooking of the eccentrically'pivoted disk II may be effected by various means.

l/Vhat I claim is 1. In the firing mechanism of a gun, the combinationof a striker-carrier, a firing tube holder pivoted thereto,.to swingtransverse to the axis of said carrier, and means for securing saidholder in firing position on said carrier.

2. In the firing mechanismof a gun, the combinationnof a removablestriker-carrier, a pivot pin located eccentrically on saidstriker-carrier, a firing tube holder in. the form of a disk mounted onsaid pivot pin, and a device on said striker-carrier for engaging andholding said firing tube holder disk in positionforfiring-;.

3.. In the firing mechanism of a gun, the combination of a: removablestriker-carrier, a pivot pin located. eccentrica'lly' on saidstriker-carrier, a firing tube holder in the form of a. disk mounted: onsaid pivot pin, a slot in said firing tube holder disk, and a stud onsaid striker-carrier adaptedto engage said: slot for holding said:firing tube holder disk. in position for firing:

In testimony whereof. I have signed this specification in the presenceof two subscribingwitnesses.
